Precise Orbit Determination for Low Earth Orbit Satellites
The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two mai...
متن کاملCDMA in Low Earth Orbit Satellites
In recent years the use of small multi mission satellites (SMMS) in Low Earth Orbit (LEO) for making voice, data and E-mail communications has been grown extensively. Low production cost, Low cost of lunching and low transmission power due to it’s low orbit of these satellites are some reasons for their vast usage. How over because of their low orbit they need to turn several times around the e...
متن کاملStudy of Low-cost Orbit Determination System for Tethered Satellites
The statistics of estimated errors when conducting the orbit determination of a tethered satellite system (TSS) by only using Doppler frequencies is shown. TSS consists of two satellites connected each other by a tether. The center of mass (CM) moves like a single satellite, so this system can be utilized in case of a single satellite as well as TSS. This is considered as a low-cost orbit deter...
متن کاملOn the Mitigation of Solar Index Variability for High Precision Orbit Determination in Low Earth Orbit
Effective satellite mission operations are directly impacted by the ability to generate accurate and precise orbit predictions. High precision orbit determination processes rely on detailed force models to propagate an orbit solution and predict future orbit behavior. While gravity forces are typically well understood, the modeling of non-conservative forces is often more challenging, causing i...
متن کاملLow-Earth Orbit Determination from Gravity Gradient Measurements
An innovative orbit determination method which makes use of gravity gradients for Low-Earth-Orbiting satellites is proposed. The measurement principle of gravity gradiometry is briefly reviewed and the sources of measurement error are analyzed. An adaptive hybrid least squares batch filter based on linearization of the orbital equation and unscented transformation of the measurement equation is...
